The capabilities of our designed charging device for charging of lead-acid batteries with sulfated plates by pulse asymmetric current were tested experimentally. The principle of the considered charging mode is based on alternation of short high-amplitude pulses of the charging current with discharging current pulses with their sequence frequency being multiple of the alternating current frequency in Russia (50 Hz). The designed device enables effective charging of lead-acid batteries with deeply sulfated plates, and is suitable for primary battery formation of lead-acid batteries and for restoration of the initial capacity of batteries in the process of their long-term exploitation.
